' :1.10 holding a filter sheet, especially a paper lter sheet on aperforated support for the ground coffee.

p The filter sheet is used to prevent the ground coffee passing throughthe perfo- "15 rated support and it has been found that `if this sheetlies loose on the perforated support, it is frequently displaced inplacing 1 Y u l Y y A d j u n Y the seemed eelee ie Pleeeel en thefilter sheet, that the ground coffee frequently gets bethe support Withthe ground coffee in position in an urn. With the aid of this present1.20 invention such displacement is prevented with the result that whenthe coffee is made there is no possibility of any grounds having fallenthrough into the bottom of the vessel, that is, into the coee beverage.
